Product FAQs
5 answersWhich panelboards are compatible with the Siemens B330HH circuit breaker?
The B330HH is designed for installation in Siemens P1, P2, P3, P4, and P5 panelboards that accept bolt-on Type BL or HBL series breakers.
What does the HH suffix in the B330HH catalog number indicate?
The HH designates this as a Type HBL breaker. This frame provides a high interrupting capacity of 65kA at 240V AC, which is significantly higher than standard BL or BLH versions.
What wire sizes are accepted by the terminal lugs on the B330HH?
The built-in lugs accommodate 14 to 6 AWG copper conductors or 12 to 6 AWG aluminum conductors. Ensure proper torque is applied during installation as specified on the breaker label.
Can the Siemens B330HH replace older ITE bolt-on breakers?
Yes, Siemens acquired ITE, and this breaker serves as a direct replacement for legacy ITE 30A, 3-pole bolt-on breakers that share the HBL frame and 65kAIC rating.
How does the thermal-magnetic trip unit in the B330HH protect electrical circuits?
The thermal component provides long-time delayed tripping to prevent overheating from continuous overloads, while the magnetic component offers instantaneous tripping to quickly clear severe short circuits.
